GAPlPING- OFF DEVICE.

To all whomt't may concern:

Beit known that-I, HARRY F. Hrrunn, a citizen of the United States,residing at Mount Vernon, in the county of Knox and State of Ohio, haveinvented certain new and useful Improvements in Capping-Cit Devices, ofwhich the following is a specification. v

The invention relates to capping-oil devices for capping off glasscylinders by means of an electrically heated wire. It has for itsprincipal objects; the provision of a device of the. character specifiedwherein the wire'is automatically maintained in engagement with thecylinder with a fixed and predetermined amount of pressure; the promsionof wire supporting means whereby the slack incident to the lengtheningof the wire when heated is yielding-1y taken up; and the provision of anarrangement of the Wire.

' wherein the entire circumference of the cylelectrioity,,andis securedat one-end. to the inder is ex osed to contact with the wire.

One embodiment of the invention is illus-- in the accompanying drawmgs,

trated wherein:-

Figure 1 is a side elevation of the device,

Figure 2 is a side elevation of the reverse side of the device,

Figure 3 is an end view, and

Figurev 4 is a detail section through the reel showing the arrangementof the spring.

Referring to the drawings, 1 is the supporting frame work of theapparatus which framework is' provided at its rear end with a handleportion 2 adapted to be grasped by the hand. Mounted'rotatably upon thesup.-

port l is the wheel or real 3 providedwith a groove .4: (Fig. 3) forreceiving)' the wire 5 This wire 5 is of small-diameter sothat reel,while the other end "is adapted to 'encircle the glass cylinder to becapped. oil. The loose end 6 of this wire after 'iassing around thecylinder crosses the wire as indicated in Figure 1, and is secureddetaohably to the screw 7. A pair of metal blocks 8 and 9 are secured tothe front end ofthe support 1, and current'is applied to such blocks bymeans ofthe wires 10 and 11 leadin to a generator of some-description.The b ook 8 is provided with a passage 12 (Fi 3) through which the wirepasses, and the. lock 9 is provided with a groove 13 (Figs l and 3)through which the end 6 of Specification of Letters Patent. PatentedMar, 12, 1912, Application filed December 19, 1908. Serial llo. 468,275.

the wire is carried before it is wound about the holding screw 7. Byreference-toFig. 3 it will be seen tliat'the opening 12 and the groove13 lie in different planes so that the ends of-the wire pass ea'chotherWithout contacting. It will be apparent that by making the ends of thewire cross or pass 'yieldingly applied to the wire 5 to hold it tightaboutthe cylinder, and take up any slack due to the expansion of thewire after the end 6 thereof has been secured in position about theholding screw 7.. The device is thus adapted to automatically maintainthe Wire in engagement, with the cylinder with a fixed and predeterminedamount of prcssure, and is adapted to operate in connect-ion withcylinders of varying diameters. The flow of current through the wirecoir veniently controlled by means of a switch 15 mounted upon the sideof the support 1,

which switch is preferably of the type shown wherein the'flow iscontrolled by means of ,a'pair of push buttonslfi and 17, whichconstructionis well known in the art and needs no further description.The various advantages incident to the construction (will be apparent tothose skilled in the art.

Having thus described'my invention and illustrated its use, what I claimas new and desire to secure by Letters Patent is the following l. Acapping ofi device for glass cylinders comprising a circle of wirehaving its ends crossed and in contactwith the cylind-er at the point ofcrossing but out of contact with each other at snub point, a. reelto,wh1ch one end of the wire is attached, a 5];1H'lg tending to rotatethe reel for hold- -ing the-reel in teusion when applied toe cylinderand means for sending a Cl'lli'tltt of electricity through the wire.
